[0002] The top condenser reflux unit is a core piece of equipment for separating mixtures in chemical, pharmaceutical, and laboratory fields. It achieves efficient mass transfer and separation of gas and liquid phases by condensing steam and refluxing it back into the tower. The condenser reflux unit is assembled from multiple parts, which facilitates disassembly and inspection. When the external piping of the condenser reflux unit is disconnected, the inlet and outlet pipes of the condenser reflux unit will be exposed. In order to prevent foreign objects from entering the inlet and outlet pipes, sealing devices are installed on the inlet and outlet pipes to avoid trouble. Utility Model Content

[0003] The main objective of this invention is to provide a combined tower top condensation reflux device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A combined tower top condenser reflux device includes a condenser body. An upper cover is fixedly installed at the upper end of the condenser body, and a lower cover is fixedly installed at the lower end of the condenser body. Connecting pipes are installed on both the upper and lower covers. Bolt and nut assemblies are installed between the condenser body and both the upper and lower covers. Track rods are fixedly installed on the front surface near the top and the rear surface near the bottom of the condenser body. Folded protective covers are installed inside the track rods at both the upper and lower ends. Protective covers are installed on the track rods. An inlet pipe is installed on the front surface of the condenser body above the track rods, and a outlet pipe is installed on the rear surface of the condenser body below the track rods.

[0005] More preferably, the track rod has a groove inside, a guide rod is fixedly installed inside the groove, and a spring is sleeved on the surface of the guide rod.

[0006] More preferably, the lower inner surface of the upper protective cover and the upper inner surface of the lower protective cover are both provided with slots, and a sleeve block is fixedly installed inside the slot, and the sleeve block is sleeved on the guide rod.

[0007] More preferably, one end of the folding protective cover is fixed to the sleeve block, and the width and length of the protective cover are both greater than the diameter of the inlet pipe and the outlet pipe.

[0008] More preferably, baffles are fixedly installed on both the front surface of the condenser body above the inlet pipe and the rear surface of the condenser body below the outlet pipe, and the protective cover is in contact with the baffles.

[0009] Compared with the prior art, this utility model proposes a combined tower top condenser reflux device, which has the following beneficial effects: In this invention, by setting up a condenser body, a track rod, and a protective cover that work together, when it is necessary to connect the external pipeline to the input and discharge pipes, the protective cover is pushed to expose the input and discharge pipes. During this process, the spring is compressed due to the movement of the protective cover. When the external pipeline is disconnected from the input and discharge pipes, the spring will push the protective cover to move and automatically block the input and discharge pipes. After the moved protective cover contacts the baffle, it can block the input and discharge pipes without the need for a separate sealing device. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1-4 As shown, a combined tower top condenser reflux device includes a condenser body 1, an upper cover 2 fixedly installed at the upper end of the condenser body 1, a lower cover 3 fixedly installed at the lower end of the condenser body 1, connecting pipes 4 installed on both the upper cover 2 and the lower cover 3, bolt and nut assemblies 5 installed between the condenser body 1 and the upper cover 2 and the lower cover 3, a track rod 6 fixedly installed on the front surface near the top and the rear surface near the bottom of the condenser body 1, a folding protective cover 10 installed inside the track rod 6 at both the upper and lower ends, a protective cover 7 installed on the track rod 6, an inlet pipe 8 installed on the front surface of the condenser body 1 above the track rod 6, and a discharge pipe 9 installed on the rear surface of the condenser body 1 below the track rod 6.

[0016] In a preferred embodiment: a groove 601 is provided inside the track rod 6, a guide rod 602 is fixedly installed inside the groove 601, and a spring 603 is sleeved on the surface of the guide rod 602.

[0017] In the above structure, the spring 603 is in an extended state in its natural state, and the elastic coefficient of the spring 603 must ensure that after the external pipelines installed with the input pipe 8 and the discharge pipe 9 are disassembled, the spring 603 can push the protective cover 7 and make the protective cover 7 contact the baffle 101. In this way, the protective cover 7 and the baffle 101 can cooperate to cover the exposed input pipe 8 and discharge pipe 9.

[0018] In a preferred embodiment, a slot 702 is provided on the inner lower surface of the upper protective cover 7 and the inner upper surface of the lower protective cover 7. A sleeve block 701 is fixedly installed inside the slot 702 and is sleeved on the guide rod 602.

[0019] In the above structure, when the sleeve 701 is fitted onto the guide rod 602, the protective cover 7 is always connected to the track rod 6, and the movement trajectory of the protective cover 7 is limited.

[0020] In a preferred embodiment: one end of the folding protective cover 10 is fixed to the sleeve block 701, and the width and length of the protective cover 7 are both greater than the diameter of the inlet pipe 8 and the outlet pipe 9.

[0021] In the above structure, since the folding protective cover 10 is installed inside the track rod 6 and one end of the folding protective cover 10 is fixed to the sleeve block 701, when the protective cover 7 moves, the folding protective cover 10 will move in a telescopic motion along with the movement of the protective cover 7, and the folding protective cover 10 has a certain shielding effect on the groove 601.

[0022] In a preferred embodiment, baffles 101 are fixedly installed on both the front surface of the condenser body 1 above the inlet pipe 8 and the rear surface of the condenser body 1 below the outlet pipe 9, and the protective cover 7 is in contact with the baffles 101.

[0023] When this utility model is in use, if it is necessary to connect the external pipeline to the input pipe 8 and the discharge pipe 9, push the protective cover 7 so that the input pipe 8 and the discharge pipe 9 are exposed. During this process, the spring 603 is squeezed due to the movement of the protective cover 7. When the external pipeline is disconnected from the input pipe 8 and the discharge pipe 9, the spring 603 will push the protective cover 7 to move and automatically block the input pipe 8 and the discharge pipe 9. After the moved protective cover 7 contacts the baffle 101, it can block the input pipe 8 and the discharge pipe 9. There is no need to install a separate sealing device to block the input pipe 8 and the discharge pipe 9.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
